Behavioral thermoregulation in the California Sea Lion

Behavioral Biology, 1974
Behavioral thermoregulation in the California sea lion, Zalophus californianus, was studied during the summers of 1970 and 1971 on San Nicolas and San Miguel Islands, California. Zalophus has a series of behavioral responses which correlates with the rate of radiant input.

An epizootic of leptospirosis in California sea lions

Journal of the American Veterinary Medical Association, 1985
SUMMARY Between May and December 1984, an epizootic of leptospirosis in California sea lions (Zalophus californianus) occurred along the west coast of the United States from Monterey County, Calif, northward to Seattle, Wash. Clinical signs observed were severe depression, excessive thirst, and tucked-up posturing, with associated leukocytosis and ...

Lateralised swimming behaviour in the California sea lion

Behavioural Processes, 2006
Lateralised motor behaviour in the pinnipeds has been subject to little investigation. This study examined the swimming behaviour of seven zoo-housed California sea lions to determine whether they exhibited a directional bias in their motor behaviour.

COCCIDIOIDOMYCOSIS IN A CALIFORNIA SEA LION (Zalophus californianus)

Journal of Wildlife Diseases, 1976
Coccidioidomycosis in an adult male California sea lion (Zalophus californianus) is described. The animal was housed in a zoo in Tucson, Arizona, for approximately 5 years. This is believed to be the first reported case of coccidioidomycosis in a marine mammal.

Toxoplasmosis in a California Sea Lion (Zalophus californianus)

American Journal of Veterinary Research, 1977
SUMMARY Disseminated toxoplasmosis was diagnosed in a female California sea lion that had been used in thermoregulation studies for about 4 years while housed in a small enclosure with a fresh-water pool at the University of Hawaii, Honolulu. Toxoplasma gondii was demonstrated in and around necrotic lesions of the heart and the stomach.

Underwater Visual Discrimination by the California Sea Lion

Science, 1965
Two captive sea lions ( Zalophus californianus ) presented with a series of size-discrimination tasks showed preferences for the smaller of two targets and gave virtually errorless performances despite changes in the form and relative size of the targets.

Cambered profile of a California sea lion's body

Journal of Experimental Biology, 2015
More than 100 research articles have referred to an experimental study by [Feldkamp (1987][1]) on the California sea lion, which mentions that its body resembles a symmetric airfoil, NACA 66018. We believe that perhaps an oversimplification has been made in this comparison.

Viral Hepatitis (Adenovirus) in a California Sea Lion

Journal of the American Veterinary Medical Association, 1981
SUMMARY A juvenile California sea lion (Zalophus californianus) died 28 days after admission to the California Marine Mammal Center. Necropsy revealed hemorrhagic fluid in the stomach and hepatomegaly. Histologically, there was evidence of multifocal necrotizing hepatitis and acute suppurative bronchopneumonia.

Water Balance in California Sea Lions

Physiological Zoology, 1970
which these animals haul out are truly desert islands, as dry and nearly as hot as the nearby mainland. These sea lions have no access to fresh water. The question naturally arises, do they drink sea water? If they drink sea water, they must somehow get rid of the salts.
